ALBERT G. HUMPHREY, OF NEOGA, ILLINOIS.

HORSESHOElNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 238,906, dated March15, 1881. Application filed October 14, 1880. (No model.)

To all whom it may concern Be it known that I, ALBERT G. HUMPHREY, acitizen of the United States, residing at Neoga, in the county ofCumberland and State of Illinois, have invented new and usefulImproveinents in Horseshoeing Machines, of which the following is aspecification.

The subject of my invention is a machine for cutting off and clinchingnails after they are driven in the usual manner in shoeing horses.

The machine consists, essentially, of a stationary horizontal knife anda sliding vertical bit and clincher, with devices for holding them inrequired position on the upper surface of the hoof, and a cam-lever, bywhich the sliding knife and clincher are driven to cut off the nail byacting shearwise with the stationary knife and at the same moment toeffectually clinch the nail.

The object of the invention is to save labor and time in shoeing horsesand to avoid a fruitful source of disease in the present mode ofclinching and cutting off the nails.

In order that the invention may be fully understood,I will proceed todescribe it with reference to the accompanying drawing, which representsa vertical section of the machine.

A is a solid block of metal, which is made of substantially the shapeshown, to adapt it for application to the upper or outer surface of thehoof and to form a stock for the working parts, as hereinafterdescribed.

B is a cam-lever, fulcrumed at b in theupper part of the stock A.

C is a bit sliding vertically within the stock A, in position to beforcibly pressed down by the cam-lever B.

H is a spiral spring seated on a suitable collar or shoulder in thestock A, and bearing upward against a head or collar at the upper end ofthe shank or bit 0, for the purpose of lifting the said bit whenreleased by the camlever.

D is a rest provided with a set-screw, E, and adapted to slide on avertical stud, F, so that it may be fixed at any required height bymeans of the set-screw E.

G is a stationary knife fixed in the face of the stock Anear its base,as represented, so that the sliding bit C may act shearwise with thesaid knife. A cavity, I, is formed in the face of the stock A near itsbase, within the point at which the knives O and G meet, to afford roomfor the projecting points of the nails audpermit the escape of thecuttings. The working-face of the bit G is formed, in addition to thecutting-edge c, with a succession of shoulders, 0, adapted for catchingthe projecting end of the cut nail and bending and clinching it closelydown against the surface of the hoof, as required.

The operation of the machine is as follows: The nails having been drivenin the usual manner, the rest D is set to the required height to suitthe hoof, and the machine is then applied with the edge of the hoofextending within the angle between the said rest and the base of thestock A, and the head of the nail bearing on the rest, the rest havingbeen so adjusted as to bring the sliding bit 0 vertically over theprojecting nail which is to be cut off and clinched. The lever B is nowbrought down, which urges the sliding bit 0 downward with great force,bending over the nail and bringing its projecting end over thecutting-knife C, so that the point is cut off, leaving therequiredendforclinching. Thecontinueddownward movement of the bit 0bends and presses the projecting end of the nail closely over thesurface of the hoof and effectually clinches the same by the resistanceafforded by the rest D under the head of the nail. I thus dispenseentirely with the use of the hammer, of the customary clincher forclinching nails, and of the rasp for cutting off the same, and therebyrelieve the hoof from violence and injury which are caused by theconcussion of the hammer under the usual mode of clinching.

Having thus described my invention, the following is What I claim as newtherein and desire to secure by Letters Patent:

1. The horseshoeing-machine consisting of a block, A, horizontal knifeG, sliding vertical bit (J, and cam-lever B, as set forth.

2. The combination of block A, having horizontal knife G and stud F, thefoot-rest D, camlever B, and vertical sliding bit 0, as set forth.

3. The bit 0, having knife 0 andshoulders c, in combination with blockA, cam-lever B, and knife G, as set forth.
